Learning Goal Internal Energy of an ideal gas The internal energy of a system is the energy stored in the system. In an ideal gas, the internal energy includes the kinetic energies (translational and rotational) of all the molecules, and other energies due to the interactions among the molecules. The internal energy is proportional to the Absolute Temperature T and the number of moles n (or the number of molecules N). n monatomic ideal gases, the interactions among the molecules...
The internal energy of an ideal gas can be derived using statistical mechanics as U=U(S,V)=αNkB(N/V)2/3 e2S/3NkB where α is a constant. Show that this expression leads to the equation of state for an ideal gas pV = NkBT. (What is dU?)
A gas is compressed by a piston in a cylinder from an initial pressure of 10 psia, initial volume at 40 ft^3 to a final pressure of 20 psia. During the compression process, the product pV remains constant. If the change in internal energy to the gas is 10 Btu, determine the amount of heat transferred from the system. (1 Btu = 778.17 ft-lbf)
